Ah... no, but I understand it has been made to work. (E.g., PuTTY uses 
it AFAIK, and that works fine here.) Don't know how easy it is to get 
hold of source...

Alternatively, would it be simpler for me to track down the source for 
the Unix "md5sum" program and do some FFI on that? (Bearing in mind, I 
don't know how FFI works and I don't know C.)

The final alternative is that I just call MD5SUM.EXE from my Haskell 
program and try to parse the output. But that strikes me as rather messy.
